Wondering how to choose the best anti-aging hair colour to cover your grey hair and get the best results? You can't go wrong with these five easy tricks.

  1. Colour with a permanent formula

It’s no secret. If more than 50% of your hair is grey and you want to cover it, no more tone on tone formula. It's time to get serious with permanent hair colour. It's designed to cover grey hair and give long-lasting results. Because if you're going to colour your hair, you might as well enjoy it for six to eight weeks, right? 

  1. Track down the formula that guarantees 100% coverage of grey hair

You don't want to cover your white hair just a little. You want to cover them ALL, to not leave one behind and, if possible, to admire the results for more than just a week. There are several formulas on the market. Look at the boxes in the aisles and take only those that guarantee a 100% coverage. And while you're at it, take two boxes. You wouldn't want to run out of hair colour half way through.

  1. Double the hair colour

If you have the impression that your grey hair is endowed with super stubborn powers, rest assured. It's impossible. But this may mean that you should double the hair colour in your formula. In the Nutrisse line, look for colour creams whose numbers end with double zeros such as colours 400, 500 and 600. These rich shades of espresso contain more pigments and are very effective against grey.

  1. Apply like a pro

To stand victor against grey hair, it is also necessary to apply the hair colour correctly. As a good student, be careful, follow the steps and setting time. But if you had to remember three things to improve your application technique and get the grey out, here they are:

- Make sure your hair is free of styling product or make-up residues. They can create a barrier that prevents the pigments from properly penetrating the core of the hair fibre.

- Always start with the areas that are most visible such as the temples and the top of the head. You will be certain to have eliminated as much grey hair as possible and this will give an extra time for the pigments to settle.

- Work the emulsion: it ensures a more uniform application, a better white coverage and... a more radiant colour.

  1. Prolong the setting time.

Want to get rid of stubborn greys? So, for once, you have the right to cheat. Add an additional five minutes to your hair colour's setting time. This will allow the pigments to penetrate to the core of the hair fibre. And remember, as after each hair colour, wait 48 hours before shampooing. You really want to give the pigments time to settle so that you can admire the results for weeks to come.
